OST Required Configurations
This topic introduces three possible required configurations to enable OpenStorage Technology (OST) operations: DR
Series system and a DMA-based media server or client (for example, OST operations that support a NetBackup-media
server, a Backup Exec-media server, or a Backup Exec-client).
最佳做法：OST 和 DR Series 系统
本主题介绍对 DR Series 系统使用 OpenStorage 技术 (OST) 操作的一些最佳做法建议。
• OST 和非 OST 容器可存在于同一 DR Series 系统上。DR Series 系统支持同一设备上拥有 OST 和非 OST 容
器。然而，这可能导致容量报告错误，因为两个容器类型共享相同的底层存储。
• OST 复制和非 OST 复制在同一 DR Series 系统上。非 OST 复制需要进行配置，并按容器进行复制。然
而，这种类型的复制不会复制 OST 容器。OST 复制是基于文件的，由 DMA 触发。
• 请勿将容器连接类型从 NFS/CIFS 更改为 OST。必须先删除非 OST 容器，然后才能将此容器创建为同名
OST 容器。
设置客户端侧的优化
客户端侧的优化过程可节省备份操作的执行时间，并降低网络上的数据传输开销。
可使用 DR Series 系统 CLI 命令 ost --update_client --name --mode 开启或关闭客户端侧的优化（又称为客户端侧
的重复数据消除）。有关 DR Series 系统 CLI 命令的更多信息，请参阅 Dell DR Series System Command Line

Configuring an LSU
You can configure a logical storage unit (LSU) as an OpenStorage Technology (OST) connection type container for data
storage by using the DR Series system GUI. To configure an LSU as an OST connection type container, log in to the DR
Series system and complete the following:
1. Navigate to the Containers page (in the Dashboard navigation panel).
2. Click Create to create a new container.
The Create New Container dialog is displayed.
3. In Container Name, enter a name for the container.
4. In Marker Type, select the None marker type.
For OST operations, only the NetBackup and Backup Exec media servers are supported.
5. In Connection Type, set the container type to OST.
The OST pane is displayed, and this is where you can set the capacity for the OST connection type container.
6. In Capacity, select either the Unlimited or Size options to set the capacity for the OST connection type container.
If you select Size, make sure to define the desired size in Gibibytes (GiB).
7. Click Create a New Container (or click Cancel to display the Containers page).
注: For general information about creating DR Series system containers, see Creating Containers, and for creating
an OST connection type container, see Creating an OST or RDS Connection Type Container.
